Sen. Marco Rubio, R-Fla., speaks during a debate with Rep. Patrick Murphy, D-Fla., at the University of Central Florida, Monday, Oct. 17, 2016, in Orlando, Florida.

Sen. Marco Rubio of Florida warned his Republican colleagues not to discuss the WikiLeaks dump of emails stolen from Hillary Clinton's campaign chair John Podesta.

"I will not discuss any issue that has become public solely on the basis of WikiLeaks," said Rubio in a statement to NBC News, breaking with Donald Trump's approach. "As our intelligence agencies have said, these leaks are an effort by a foreign government to interfere with our electoral process and I will not indulge it."

Rubio did not mention Trump by name, but he is clearly departing from his former rival on the issue. Trump has repeatedly brought up the WikiLeaks' hack, accusing the media of ignoring the stolen emails in an effort to protect Clinton.

"I want to warn my fellow Republicans who may want to capitalize politically on these leaks," Rubio said. "Today it is the Democrats. Tomorrow it could be us."
